ROBERT P. GARSED, OF NORRISTOWN, PENNSYLVANIA.

ANNUNC IATOR-R ESTORING DEVICE.

SPECIFICATION forming part of Letters Patent No. 458,160, dated August25, 1891.

Application filed March 23, 1891- To all whom it may concern.-

Be it known that 1, ROBERT P. GARSED, a citizen of the United States,residing at Norristown, county of Montgomery, and State of Pennsylvania,have invented a new and use ful Improvement in Annunciator-RestoringDevices, of which the following is a specification, reference being hadto the accompanying drawings to more fully illustrate the device.

The object of my invention is to produce a pneumatic restoring devicethat can be ap-. plied to annunciators, whether electric or pneumatic orother kinds. The inventionrelates also to improvements on my patent, No.242,297, May 31, 1881.

Referring -to the drawings, Figure 1 is a front view of an annunciator,showing the device applied to thebottom end of the restoring-rod beneathsuch annunciator. Fig. 2 is a part sectional view of Fig. 1 through theline 00, and also shows a pneumatic push-lever for operating saidrestoring device. Fig. 3 is a connecting-tube suited for placing in agroove in the rear of annunciator when connection is made beneath theannunciator. Fig. 4 is a rear view of an annunciator, showing apreferable form of my device within the annunciator. Fig. 5 is amodification showing the bellows and bracket placed upon the rear partof annunciator-case. Fig. 6 is the form of bellows-bracket best suitedfor placing beneath the annunciator, and Fig. 7 shows a covering-boxbest used for the apparatus when placed beneath an annunciator.

A represents an annunciator-case, preferably having a back B attachedthereto.

0 is a bellows-bracket, and is suited to support an operating-bellowseither outside or within the annunciator.

D is an inflatable body or bellows, and is supported upon the bracket 0and connected with the pipe E.

F is an air-lever adapted to force air through pipe E to bellows D.

G is a bellows-weight, and serves to collapse the bellows after the samehas been inflated in the operation. of the device.

H is a restoring-rod handle, and when the restoring device is placedbeneath the annunciator it is of use when desirable in operating therestoring-rod by hand.

case may swing upon its hinges.

face of annunciator, and with its slot J guides said handle H in itsmotions, and when fastened to the covering-box K serves, as well as tocover the opening in said box, to retain said box in place.

L is a guide-pin, and when used on the weight G guides it in its motionsupon bellows D.

M is a lifting-arm or projecting part, and

when the restoring device is placed within the annunciator-case its oneend is fastened to the restoring-rod N of the annunciator, and its otheror outer end engages the top of bel lows, as shown.

O are holes in the ribs q of the bracket 0 and serve withcorrespondingholes P in the box K to retain said box to said bracket bysuitable screws, said ribs q serving as well to strengthen the parts ofbrackets 0 when so made. The holes R in the outwardly-proj ecting endsof the brackets G serve, with ordinary hooks that may be placed on thesides of the annunciator, to keep said sides in position, as may bedesired, and the downwardlyprojecting bifurcated ends S, integral withsaid bracket, serve to fasten the annunciator in a suitable positionwhen said bracket is I is a plate suited to fasten on the bottomfastened to said annunciator, as will be un- 1 derstood.

When the restoring device is placed within. the case A and there is ahinged back torsuch case, the part of the pipe E extending within saidcase is best flexible, so that said back or The groove shown in saidback permits the pipe to be placed within it The operation of the deviceis as follows: After any of the indicating mechanism of an annunciatorhas been operated in any of the well-known ways by electricity, air, orotherwise, and it is desired for any reason to restore the indicatingmechanism, the same may be done by compressing the lever F, which maybeany air-compressing device suited to force air to the bellows D, andby inflating said bellows the restoring-rod N is made to rise throughthe medium of the arm M or the equivalent, the projecting part Nengaging the bellows, as before stated, with the result that theindicators or arrows that may have been operated in any of thewell-known ways to indicate the point from whence such oper-' ationcomes are restored in this instance by the arrows being raised throughattached mechanism.

In Fig. 5 the arm H engages or disengages the top of the bellowsrespectively, as the back of the case may be shut or open.

In Fig. 4 the restoring mechanism is placed within the annunciator-caseand is preferably so used in electrical annunciators, as there is roomfor the pneumatic apparatus, it being understood there is difficulty inrestoring by electrical means, as the attraction of magnets is notsufficient, unless by complicated mechanism, to give a sufficient riseto said restoring-rod, and hence the advantage of pneumatic restoringmeans will be apparent, it being further understood that in many places,for various reasons, annunciators are set at such a distance from theattending person that it is very inconvenient, if not impossible, torestore by hand.

The covering-box shown in Fig. 7 should be made with an opening in itsfront face in form as shown, that the handle H may be operated.

When the device is placed beneath the annunciator, the guide-pin L(shown in Figs. 4 and 5) has its equivalent in the projecting part N',(shown beneath the annunciator in Fig. 4;) also the part of the bracketC receiving this guide-pin through it has its equivalent with thischange of position of actuating bellows in the part of annunciatorholding the part N and allowing it to work up and down.

I do not deem it necessary to show other forms of an annunciator towhich my invention can be applied, and hence leave out my own patents.

The weight G may be the equivalent of a collapsing spring; but it ispreferably used instead of such spring.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in an annunciator-restoring device, of anannunciator having operative indicators attached thereto and asuitably-supported bracket 0, holding an inflatable body D, therestoring-rod N, with a projecting part suited to bear upon said inflatable body, and means for operating the same, substantially as andfor the purposes set forth.

2. The combination, in an annunciator-restoring device, of anannunciator having operative indicators attached thereto, the bracket 0,suited to support the bellows D and having a part to receive the pin Land guide said bellows in its motions, the restoring-rod N, with itsprojecting arm M, and operative means, substantially as and for thepurposes set forth.

3. The combination, in an annunciator-restoring device, of anannunciator with operative indicators and a restoring-rod N, with aprojecting or engaging part, a bellows D for such engagement, asupporting-bracket C, with ribs g integral therewith, said bracket alsohaving parts S, adapted to fasten the same to a desired place, and thebox K, made substantially as described and suited to be held to saidbracket, substantially as and for the purposes set forth.

4. The combination, in an annunciator-restoring device, of anannunciator with indicating mechanism, a restoring-rod N, with aprojecting or engaging part, a bellows D for such engagement, asupporting-bracket C, with parts S, adapted to fasten the same to adesired place, the handle H at right angles to andadapted to move therod N, the box K, formed substantially as described, and the plate I,with the slot J, suited to support said box and guide the handle H inits motions, substantially as and for the purposes set forth. 7

5. The combination, in an annunciator-restoring device, of avertically-moving liftingvrod adapted to engage movable indicators,
